To quantitative analyze the performance of segmentation approaches above, several classical indices are applied for evaluation, including Accuracy, Dice, Jaccard, Precision and Hausdorff distance.
The definition of Accuracy, Dice, Jaccard (IoU) and Precision are summarized in Table REF .
Hausdorff distance is applied to measure the Euclidean distance between the predicted and GT images [1]}.
Dice is more sensitive to the inner filling of the mask, while Hausdorff Distance is more sensitive to the separated boundary.
The comparative results of different approaches is shown in Table. REF .
